In this way, the apparatus 70 is adjusted and set for a specific golfer 75. If the settings are moved, golfer 75 can reset adjusting screws 41, 59, 60, 62, and 63 to suit his specific height, body angle, shoulder angle, and body stance. When changing the club only screw 62 and 63 are adjusted.
In operation and use, golfer 75 follows the actions as indicated in the following Table 1.
In operation, as shown in FIG. 7, golfer 75 watches pendulum weight 36 and assigns notes of a conventional musical scale to the positions of weight 36. As shown in FIG. 8, golfer 75 rotates his shoulders about axis 44, while assigning the notes of the conventional musical scale DO, RE, MI, FA, SOL, LA, TI, DO, to specific angular positions of his shoulders. At the same time, golfer 75 holds the club in the conventional manner. Each of the shoulder strips or touches 31, 32, 33, 34, 35 also has a musical note assigned thereto in sequence. The correlation of the timing of pendulum weight 36, and the touching by a shoulder to toucher strips 31, 32, 33, 34, 35, and the foot action, and club swing of golfer 75 is shown in Table 1.
In FIG. 8, the locations of the club head 24 are different from the locations of the rotating shoulder. The musical notes in FIG. 8, located radially inwardly of an arc of club head 24 are the shoulder location notes. The musical notes, in FIG. 8, located radially outwardly of the arc of club head 24 are the club head location notes. For example, where the left shoulder moves through 90 degrees from DO(1) to MI(3), the club head 24 moves through 180 degrees from DO(1) to MI(3).
As shown in FIGS. 9 through 12, a second embodiment or golfer training apparatus 90 is provided. Apparatus 90 includes a guide assembly 91 and a support assembly 92 for a golfer 93. Guide assembly 91 includes a hand guide unit 100, which has a tube 111. Support assembly 92 has a higher left pipe 113 and a lower right pipe 114, both of which are supported by a support stand 115.

A right bar 121 is similarly connected to a right plate 117, which is fixedly connected to tube 111. Left plate 116 has an angle scale for measuring the angle 147 of tube 111 relative to a horizontal line which corresponds to the swing path angle. Left rod 120 is a height adjusting telescoping type of rod. Also, right rod 121 is a similar height-adjusting telescoping type of rod. Rod 120 has an etched arrow, which co-acts with the scale on plate 116 to give the angle of tube 111 relative to the horizontal.
Golfer 93 holds a golf club 123 for hitting a golf ball 118. Tube 111 has a left extension rod 125 for guiding the club path of the follow through and has a right extension rod 126 for guiding the club path of the back swing. Golfer 93 has an axis of symmetry or swing axis 144, Golfer 93 also has a body tilt angle 146. Angle 145, in FIG. 12, which is the angle of a line through the top edges of pipes 113, 114, corresponds to a shoulder angle of golfer 93.
For adjusting apparatus 90 to suit the height, arm length, body tilt angle 146 and stance of golfer 93, adjusting screws 150, 151 in respective pipes 113, 114 are provided, as shown in FIG. 12. Also, adjusting bolts 152, 153 in respective plates 120, 121 are provided, as shown in FIG. 10. Further, rods 125, 126, as shown in FIG. 1, are adjustable relative to tube 111, by pushing in or pulling out a rod 125 or 126 relative to tube 111.
The advantages of apparatus 70 and 90 are indicated hereafter.
A) Apparatus 70 and 90 can be fitted respectively to the height and arm length and shoulder angle 45, 145 body tilt angle 46, 146 of golfer 75, 93.
B) Head touching plate 15 helps to keep golfer 75 in the same position so that swing axis 44 is not changed in position. Plate 15 is located once for succeeding uses.
C) Shoulder guides 11, 12 and 125, 126 of respective apparatus 70 and 90 maintain the respective swing axes 44 and 144 without relocation, thereby maintaining an improved swing.
D) Shoulder touching strips 31, 32, 33, 34, 35 helps the golfer 75 to rotate about axis 44, and to remember the shoulder location and related club head location for the swing of each type of golf club 23.
E) Timer assembly 74 provides a visual display of a timing cycle for each swing of club 23 by golfer 75. Such timing cycle can be set to suit a most suitable timing cycle for golfer 75 by adjusting loop 38 and the length of pendulum string 37 to a desired pin 52 through 58.
F) Seeing the timing display of timer 74 and feeling the shoulder touching strips 31, 32, 33, 34, 35 and thinking the notes of a musical scale, at the same time, during a swing, helps golfer 75 to memorize the best swing for each type of club.
G) Adjusting guide 111 and setting angle plate 116 helps a golfer 93 using apparatus 90 to fit the apparatus to his height and arm length and body angle thereby improving his hand and club coordination.
H) Cost of manufacture of apparatus 90 in minimized.
